PORTABLE RADIO APPARATUS.

Application filed September 16, 1926. Serial No. 135,823.

This invention relates to improvements in portable radio apparatus.

An object of the invention is generally to provide portable radio apparatus in the form of an installation in motor Vehicles, as for example passenger cars, among "the dominant features of the invention being the construction, location, and arrangement of the various parts of the radio apparatus in such manner as to afford a high degree of elliciency in operation without marring the appearance of the car or interfering with the ease and convenience of manipulating the various car mechanisms and devices.

Another object of the invention is to provide an installation of the character described which shall utilize the electrical power ordinarily provided in the motor vehicle and otherwise utilize the vehicle strucr provide in a motor vehicle a dashboard adapted to support the various parts of a radio apparatus including the control panel in such manner as not to interfere with the location and manipulation of the various instruments and mechanisms ordinarily operated from the automobile dashboard.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the' scope of applicationwill be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,

Fig. 1 is a side elevational view of a closed type of passenger automobile, partly broken away to show the radio apparatus installation. v

Fig. '2 is a cross-sectional view taken on line 2-2 in Fig. 1, showing one form'of the antenna; 1 i 4 Fig. 3 is a fragmentary" oross-seotional view showing in detail the methodzof-mounting the antenna in the top structure of the car.

Fig 4 is a front elevat onal view of the radio apparatus.

automobile dashboard with parts of the radio apparatus mounted thereon.

Fig. 5 is a fragmentary front elevational view of the interior front side of the car body showing the mounting for the radio loud speaker.

Fig. 6 is an enlarged cross-sectional, view taken on line 6-6 in Fig. 4, portions of the radio receiving set casing being broken away to show the interior construction.

Fig. 7 is a diagrammatic view of the automobile power plant, generator, storage battery and their circuit connections with the Referring in' detail to the drawing, the

improved portable radio apparatus is. seen to comprise a closed type of passenger automobile 10 of any standard construction in which a radio receiving set indicated gen-- erally at 11 is mounted on the dashboard 12 infront of the drivers seat 13. Said automobile is provided with the usual power plant comprising a propelling motor 14 which has coupled thereto a suitable generator 15 for supplying electric power to a storage battery 16 through-a cut out 16,

ignition apparatus 17, and electric lights 18. in thewell understood manner.

The dashboard may be arranged to carry the various operating accessories, .such as the speedometer 19, light and ignition switch 20 at one end, a combination ammeter and gasoline register 21 and a clock 22 on the other end, the receiving set 11 which is preferably housed in a casing 11 and pro-, vided with a control panel 11. being mounted on the dashboard so flthat the operating knobs 11 on the control. panel are within easy reach of the driver. 1

The top or roof 23 of the car 10 may comprise an outer weather-proof covering 23 made of any suitable material, a bracmg structure comprismg cross-braces 23 concealed from view. .S'aid antenna may extend about said roof structure to form a loop or may be of any pther approved form, the

'erably installed between said coverings 23 and 23 of said roof 23 being thus naturally 'ends of the antenna being terminated in are of wooden construction, the antenna when installed in the roof structure is best located for receiving or transmltting radio signals because it is thus furthest removed and insulated from all shielding parts of the automobile. The antenna thus mounted on the bracing structure of the roof eliminates all superstructure or parts projecting or extending in and out of the car. By inorporating the antenna in the roof structure, ample space is furthermore provided for constructing the antenna relatively long and for positioning it so as to be free from directional effects.

A conductor cable 26 for the set 11 extends from the casin 11 and is referably carried behind the ashboard. aid cable by means of its conductor wires 26 connects with the storage battery 16 which serves as the A battery for the set 11. The cable conductor wires 26 connect the B battery 27 positioned under the seat 13, one of the conductor wires 26" being secured at 28 on the chassis frame of the automobile to serve as a ground. Thus, the entire metallic framework of'the automobile forms a substantial ground counter-poise.

The set 11 may be provided with radio tubes 11 which in the construction shown in the drawing, preferably are mounted in sockets 11 in a depending position in the casing 11. Any suitable provision may be made for replacing said tubes, as for example by constructing the casing 11 with the bottom hinged co'yer 11 wh1ch makes the interior of the casing. easily accessible.

A loud speaker 29 may be suitably mounted within the car body over the front wind shield 30 and connected to the set 11 through conductor wire 29, as'shown in Fig. 5.

If desired, the set-11 maybe provided with a jack 31 for connecting ear telephones '"inot shown) in circuit and a key'switch 32 or locking the set against unauthorized use, both the jack and switch being mounted on the panel 11-, as shown in Fig. 4.

Adominant feature of the invention resides in the facility with which the radio apparatus may be incorporated in an auto mobile so as to provide a highly practical and efiicient portable radio set. -The 1nvention may be applied to the automobile as part -of 1ts construction when originally manufactured, in which event the antenna \comparatively little additional expense, and

the dashboard may be constructe originally, as above described, to serveas amountmg for the radio set. Themvention may Since the upright likewise be applied to already manufactured ing the antenna onthe bracing structure interiorly of theroof upholsterlng or covering, then replacing the dashboard or bymodifying the same into one adapted to support the control and indicating devices for both the automobile and the radio apparatus, and connecting the radio circuit to receive the power from the storage battery of the power plant, as above described.

In using the invention, the radio set and antenna are installed in the car as described above leaving the interior of the car free from all obstruction or interference, the antennaxbeing concealed so as not to mar the interior decorative appearance of the car. Thus, the radio receiving set may be conveniently carried about and is always ready for use, the control knobs 'being readily manipulated by the operator from his seat.

The installation as abovedescribed also permits building and using radio apparatus of capacities substantially larger than those usually constructed for portable use, said apparatus being adapted for distant as well as local service. i

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made ofthe above invention, and as various changesmight be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying'drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. In a portable radio device, the com bination w1th the dashboard of a motor ve hicle of a casing extending behindthe dashboard and spaced .a substantial distance from the floor-board ofthe vehicle, and a radio apparatus housed in said casing having its control members extending therefrom through said dashboard to the front thereof.
